Bulk Import a Contact List from Google Sheets into Omnisend

The Scenario

You are an ecommerce marketing manager. The loyalty campaign goes live tomorrow at 9 AM. You have 2,000 new contacts in a Google Sheet — email, first name, last name, and loyalty tier — collected over the past three weeks from a referral program.

They need to be in Omnisend before the send window opens, so the segmentation rules that check for loyalty tier actually have data to work with.

The bad version of this afternoon:

  • You export the sheet as CSV
  • Open Omnisend's contact import wizard
  • Upload the file
  • Map email, first name, and last name — then realize loyalty tier is a custom field, which the wizard handles differently
  • Re-do the mapping, re-upload
  • Wait for confirmation, get partial success, dig through the error log
  • Repeat this at 8:45 tomorrow morning when you discover 200 rows failed silently.

The fast version is one prompt and the batch job runs while you finish your lunch.

The Easy Way: One Prompt in SheetXAI

SheetXAI is an AI agent inside your spreadsheet that reads the data and talks to Omnisend's batch API so you do not have to touch the import wizard or learn a new field mapping interface.

Open the SheetXAI sidebar and type:

Create an Omnisend batch job to import all contacts from this sheet — email from column A, first name from column B, last name from column C, and loyalty tier as a custom field from column D — write the batch job ID into cell F1.

SheetXAI reads the sheet, builds the Omnisend batch payload, fires the request, and writes the returned batch job ID into F1. You check the status in Omnisend or ask SheetXAI to check it for you.

What You Get

A single Omnisend batch import covering all 2,000 rows:

  • Email, first name, last name — mapped to Omnisend's standard contact fields
  • Loyalty tier — mapped to a custom field, not lost because the wizard does not support it
  • Batch job ID in cell F1 — so you can verify success without manually digging through Omnisend's admin panel
  • Zero manual field mapping — SheetXAI reads the column headers and handles the mapping itself

The batch API handles all 2,000 rows in one request. You do not have to split the list, paginate uploads, or worry about hitting per-request limits. SheetXAI handles that logic.

If some rows fail, ask SheetXAI to pull the failure details from the batch job result and write them into a new tab.

What If the Data Is Not Quite Ready

Contact lists collected from referral programs are almost never clean. SheetXAI handles cleanup and the import in the same prompt.

When email addresses have inconsistent formatting

Some rows have uppercase domains, some have trailing spaces, some have typos in the TLD.

Normalize all email addresses in column A to lowercase and trim whitespace from both ends. Flag any row where the email does not contain an @ sign by writing INVALID in column E. Then create the Omnisend batch import for the remaining valid rows and write the batch job ID into cell F1.

When loyalty tier values are inconsistent

The referral program used three different labels for the same tier across three months. You need them canonical before import.

Standardize the loyalty tier values in column D: map "Gold Member," "gold," and "GOLD" all to "Gold"; map "Silver Member," "silver," and "SILVER" all to "Silver"; same for Bronze. Then run the Omnisend batch contact import and write the batch job ID into F1.

When some rows are missing first name

About 400 rows have blank first name. You still want to import them — the email is enough — but you do not want to import blank strings into Omnisend's name field.

For any row where column B is empty, omit the first name field from the Omnisend contact payload rather than sending a blank string. Import all rows and write the batch job ID into F1.

When the sheet has duplicates from multiple collection sources

The list was assembled from three different form tools and some emails appear two or three times, each with slightly different tier values.

Deduplicate column A by email address, keeping the row with the highest loyalty tier (Gold over Silver over Bronze). Then check that all remaining email addresses are valid format. Finally, create the Omnisend batch contact import for the deduplicated list and write the batch job ID into F1.

The pattern: instead of cleaning the sheet in one step and importing in another, you describe both operations in one prompt and SheetXAI runs them in sequence.

Try It

Get the 7-day free trial of SheetXAI and open any contact list sheet, then ask it to run the Omnisend batch import. The Omnisend integration is included in every SheetXAI plan. For related workflows, see how to update contacts with custom field values or the Omnisend in Google Sheets overview.
